I picked mine up on cassette in the early 80s
Your Volume 2 is actually the first nine tracks of the Volume
3 which Mick Mercer's correspondent in 1980, Asterisk and myself all have (although Mick's copy did not have the repeat tracks and Twnidish).
Your "Volume 4" is identical to my "Volume 4" which also has the Parisians x3/Lady rough mixes like yours - in other words the REAL Volume 2 as opposed to your "volume 2") but starting with Whip and working its way back round the FoN. (Does yours also have the Radio 1 Mike Read interview tagged on the end by any chance? If so, our two "Volume 4"s are totally identical!)
Either Day I Met God and Boil In the Bag Man were added in as extras for the supposed Volume 4 we've both got or else more likely either Mick Mercer's correspondent's copy had them missing or unlisted or Mercer himself forgot to type them in. No chance is there that Mick still has his original reference materials for the Panache Ants Special after 30 years?
Whichever way, the so-called Volume 4 is
still just a glorified rework of the REAL Volume 2 and so I stick to my guns that there were only originally 3 basic compilation volumes.
